Letters Patent No. 103,997, dated June 7, 1870.

'The Schedule refene to in these Letters Patent and making part of the same.

To all whmn it mayconcern:

Be itvknown that I, ROBERT DIVEN, of thecity, county, and State of New York, have' invented a new ,and useful Improvement in Laundry Iron-Heaters, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawing for'zning part of this specification, and in whichi Figures 1 an'd 2 represent sectional elevations, at right angles to each other,iof a lanndry-iron heater constructed in accordance with my 'improveuienu Similar letters of reference indicate oorresponding parts. I i

My ilnventior. consists in a lauudry-iron heater of peculiarjconstruction, whereby an i'ncreased number of heating-;surfaces is provided for the iron's" in a heater of given'dimensions, fuel is economized, and the heater may be worked in a single or double capacity, as required, without duplication of the draught-pipe,

Referring to the accompanying drawing'--` A A represent the fire-,chambers or i'urnaces, and

B B, the grates of a'laundry-iron heater of a double construction.

O is the ash-pit, which may be common to both furuaces.

D D, the fed-openings for supplyin'g the fuel, and

which are fitted with doors, the ash-pit also being provided .with a suitable door or doors for clearing out the ashes, and with air-inletsfor keeping np the draught. i

Eis a divisiou-plate, by which the heater is made to comprse two furuaces, separate and distinct from each other, bu-t having a common' smoke or' draughtpipe, F, that is divided, for a portion of its height, by an extension of the plate E, and said' pipe furnished with a damper, G, which, accordingly, as it isturued to occnpy a Vertical position in line with the plateiE, o r to a horizontal one, on opposite sides of said plate, serves to establish draught from both furnaces A A, or from either one, as maybe required. Thus the whole heater may be worked by the two furnaces, or I either half of it only by a single furnace, which .will be a great advantageein 4laundr '-work.

The irou-holdingaudheating-surfaces I largely increase by not si'mply providing vthe sloping outside plates a a with ledges or rests b b for double 'rows of ii'ons,' the one above the other, forrning iron-holding and heatiug-surfaces, H, but, also, by providing inner and upper additional similar sui'faces, I,1of a reverse slope to the outside surfaces H, and, in additiou to these, utilizing, also, as resting-suifaces-for irons', the top J of the heate-r.

These enlargedfacilities are not only advautageous as regards the couvenience afforded for heating a number of irons, and at' ditierent places about 'or around the heater, but also as regards the economy which results in point of fuel. v

rhese advantages are due to the upward extension of the outside plates a `a, depressed arrangement of the top J, and to the. additional surfaces I, made to 'occnpy reverse iuclinati'ons to the surfaces H,,and so that an angular space, K, is established between such inner and outeriron-holding and heating-surfaces or plates, -for the heated gases to accumulate in and heat both surfaces alike. It is not absolutely'- essential, to this feature 4of. the invention, that the body of the heater should' be separated by adivision-plate, E, into separate furnaces, as shown in thedrawing.

Whatis here claimed, and desired to be Secured by Letters Patent, is-

1. The arrangemcnt of the reversely inciined ironheating surfaces H I and top J relatively to each other, and the furnace or furuaces A of the heater,`substantially as specified. i

2. The combination of the division-plate E with the furnaces A A, the smoke-pipe F, and the damper G, esseutially as shown and' desribed.
